It's an add-on item, but Amazon has a Galt New Baby Puzzle for just £2.90, which makes a great 1st or in some cases 2nd birthday present. It does actually say 18 months plus, but I suppose that's up to parent's discretion a little, because my daughter loved these after her first birthday.
The Galt Baby Puzzle s are made up of 12 pieces - actually six two piece puzzles. This one is of popular pets which will encourage baby with hand-eye coordination and problem solving whilst fitting the puzzle pieces together. They will also provide a great opportunity to learn the names of the animals and the colours of the puzzle pieces.
These simple colourful puzzles with chunky pieces will encourage early matching skills and manual dexterity.
There are various 'themes' available, like zoo animals, and are great, hardy, little puzzle pieces, great for stimulating little minds.
